NEETZoologyOrganisms and Populations
A population of animals is introduced into a new habitat with a fixed, limited amount of food and space. Which of the following represents the correct sequence of growth phases this population will exhibit as it reaches the carrying capacity?
Options
- ALag phase Phase of acceleration Phase of deceleration Asymptote
- BLag phase Phase of deceleration Phase of acceleration Asymptote
- CPhase of acceleration Phase of deceleration Asymptote
- DLag phase Phase of acceleration Population crash
Correct answer
A. Lag phase Phase of acceleration Phase of deceleration Asymptote
Step-by-step solution
When a population is introduced into a habitat with limited resources, it follows the Verhulst-Pearl logistic growth model. The population initially shows a lag phase as it adapts to the new environment and begins to reproduce. This is followed by a phase of acceleration (rapid growth) as the population size increases, and then a phase of deceleration as resources begin to become limiting. Finally, the population reaches an asymptote when the population density equals the carrying capacity (K) of the habitat, resul
